Great Barrier Reef bathymetry
July 06, 2010

This dataset provides the high-resolution bathymetry model of the Great Barrier Reef, called gbr100, an output of Project 3D-GBR. The ~100 metre-resolution gridded bathymetry dataset covers an area of about 3,000,000 km2, from the Gulf of Papua to northern New South Wales, and easterly into the offshore Coral Sea. This page provides the data in a range of formats for public download.
